據我所知，我已經安裝了MySQL Connector / Python(v1.2.3)模塊沒有問題 . 這是在CentOS 5.4上使用Python 2.7.7(Anaconda發行版，盡管在vanilla安裝上也是如此) . 我可以導入它并初始化與MySQL服務器的連接(v4.1.20) . 此服務器通過LAN訪問，而不是本地訪問 . is_connected() 方法斷言我已正確連接

>>> import mysql.connector

>>> cnx = mysql.connector.connect()

>>> cursor = cnx.cursor()

>>> cnx.is_connected()

True

但是，每當我嘗試直接通過游標命令(例如 cursor.execute("SELECT DATABASE();") )或間接通過mysql.connector方法(例如 get_database() )執行任何SQL查詢時，我都會得到相同的錯誤，如下所示：

>>> cnx.get_database()

Traceback (most recent call last):

File "", line 1, in

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1200, in get_database

return self._info_query("SELECT DATABASE()")[0]

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1434, in _info_query

cursor.execute(query)

statement))

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 612, in _handle_result

eof = self._handle_eof(self._socket.recv())

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 554, in _handle_eof

eof = self._protocol.parse_eof(packet)

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/protocol.py", line 252, in parse_eof

raise errors.InterfaceError(err_msg)

mysql.connector.errors.InterfaceError: Failed parsing EOF packet.

在此之后，似乎與MySQL服務器的連接丟失了 . 另一次運行 get_database() 的嘗試返回以下錯誤：

>>> cnx.get_database()

Traceback (most recent call last):

File "", line 1, in

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1200, in get_database

return self._info_query("SELECT DATABASE()")[0]

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1433, in _info_query

cursor = self.cursor(buffered=True)

File "/home/bgrande/software/genesis/anaconda-2.0.1/lib/python2.7/site-packages/mysql/connector/connection.py", line 1328, in cursor

raise errors.OperationalError("MySQL Connection not available.")

mysql.connector.errors.OperationalError: MySQL Connection not available.

這由 is_connected() 方法確認 .

>>> cnx.is_connected()

False

另外，我應該提到在這個局域網上的另一臺計算機上使用類似的設置(CentOS 5.5; Python 2.7.6)，我已成功使用MySQLdb模塊與數據庫進行交互 . 然而，與mysql.connector模塊完全相同的Python安裝不能(由于相同的錯誤) . 我試圖在這里提到的第一臺計算機上安裝MySQLdb，但我遇到了問題 . 我認為MySQL Connector / Python可以更容易地工作 .

我擔心這很難復制，因為它可能取決于我的具體環境 . 盡管如此，我還是希望能夠采取措施縮小問題所在的范圍 . 謝謝！
